SASH-WINDOW.

Specification of Letters Patent.

Patented March 12, 1907.

Application filed December 3, 1906.' Serial No. 346,102.

To all whom it wwf/y concern:

Be it known that I, PAUL KUPELwiEs'ER, a subject of the Emperor of Austria, residing at Brioni, near Pola, in Istria, Austria, have invented certain new and useful Improvements in Sash-Windows, of which the following is a speciiication.

This invention, which is an improvement on that described in the speciiication to actuates a catch which when the sash is in its highest position holds the upper sash, so that when the middle sash is again lowered it is not followed by the -upper sash. The next time the middle sash is raised it again actuates the catch to bring it out of engagement with the upper sash,`so that on the subsequent lowering movement both sashes move together. The side rails, which serve to close the joints between the `window-sashes and the window-frame, are made to fold back, and each keeps pressed against all the window-sashes by a single actuating device in the several positions of the sashes. For this purpose there is arranged in each side rail a vertically-sliding rod having wedge-shaped surfaces at suitable distances apart and connected with a handle, by turning which the rod may be moved to bring the wedge-shaped surfaces in or out of engagement with hooks on the window-frame, and thus to press the side rails against the sashes or to liberate the rails.

In the accompanying drawings, Figure 1 is an elevation from the inside of a sash-window constructed according to the invention, the sashes being closed. Fig. 1a is a part longitudinal section showinga detail. Fig. 2 is a vertical cross-section on line A A of Fig. 1. Fig. 3 is a like view to Fig, 1, the middle sash being raised. Fig. 4 is a vertical cross-section on line B B oi Fig. 3. Figs. 5 and 6 are sectional views of` the upper parts of Figs. 2 and 4, respectively, `drawn to an enlarged scale, Fig. 6 being shown partly in elevation.

Figs. 7 and 8 are views of a detail in two dif- 'ferent positions. Fig. 9 is a horizontal section on line A B of Fig. 8. Figs; 1() and 11 are views showing a detail in two positions.

The sash-window comprises three sashes 1,

2, and 3, situated in the same vertical plane and guided laterally in the window-frame 4. j

The middle sash is the biggest and is moved by hand with aid of a grip 5. It is connected with the lower sash 1 by means of pulleygear in such a manner that `when it is raised the lower sash 1 is lowered into the hollow casing 6, Figs. 3 and 4, and when it is lowered again the lower sash is raised again until the two close together, Figs. 1 and 2. Each pulley-gear consists, preferably, of a nickel band 3, guided over a pulle 7 andconnected at one end with the midd e sash at 9 and at `the other end with the lower sash at 10. The lower sash 1 is preferably connected by hinges 13 with the frame 12, situated in the hollow casing and duly guided therein. Thus when the sash 1 is in the raised position it may be turned on the hinges 13. The frame 12, which is provided with a weight 14, if necessary, insures'by its weight the descent of the .lower sash 1 when the middle sash 2 is raised.

On an upper and preferably hinged crossrail 15 of the window-frame 4 there is fixed a catch consisting of a hook 1.7, pivoted in a casing 16 of the catch. This hook is kept by a spring 18 against a `cam 19. This cam is fixed to a ratchet-wheel 20, having four teeth and actuated by `a pawl 21, whichis pivoted at 22 to a lever 23, which projects below the cross-rail and turns on the pin 24. The pawl 21 has a lateral extension subject to the pressure of the spring 18. In the position of the parts shown in Fig. 10 the hook 17 is withdrawn into the casing, resting against the narrower portion of the cam 19.

When the middle sash 2 is raised, a projection 25, which it carries, strikes the lever 23 shortly before the sash is in its highest position. The lever 23 is thus pressed into the casing and the pawl 21 engages with the ratchet 20, turning it through a portion of a revolution, so that the cam 19 is turned to press the hook 17 through a slot 26 in the Jr'ront Wall of the casing 16, in which position it engages in an eye 27, Figs. 2 and 4, carried by the upper sash 3. Ii now the middle sash 2 be lowered again, the upper sash is left behind, because the hook 17 remains under the influence of the wid er portion of the cam 19- that is to say, engaged in the eye 27, Figs. 3, 4, and 6. In this manner a side windowopening is formed. When the middle sash 2 is again raised, the catch is again actuated ICO IIO

by the projection 25, so that the hook 17 is again Withdrawn into the casing 16, Fig. 10, and the upper sash 3 is free to follow (owing to its weight) the middle sash 2 when this is subsequently lowered. Since the ratchetwheel 20 possesses four teeth and the cam 19 has the form of a rectangle, the hook 17 is alternately brought in and out of engagement With the upper sash when the lower sash is raised.

For closing the joints between the windowsashes and the window-frame a hinged rail 28 is xed on the inside of the frame at each side of the window. According to this invention each rail can be pressed against all the window sashes in whatever position these may be by means of a single handle in order to fasten the sashes in the position in which they happen to be, besides closing the aforesaid joints. For this purpose the arrangement is as follows: On the inside of each rail 28 is a rod 29, suitably guided to slide in the direction of its length. This rod can be raised and lowered by any suitable device actuated by hand-for instance, as here shown, the rod may be connected by a link 31 to an eccentric that can be turned by a handle 30. On the rod 29 are fixed, at suitable distances-from each other, wedgeshaped projections 32, and beneath each of these is a slot 33. When the rails 28 are closed against the window-frame 4 and the rods 29 are in their raised positions, Fig. 7, hooks 34, fixed to the window-frame 4, can pass through the said slots. If now the iandle 30 is turned upward, Fig. 8, all the wedge-shaped projections 32 engage beneath the noses of the corresponding hooks 34, so that the preferably projecting edges 35 of the rails 28 are firmly pressed against the window-sashes, Fig. 9, and the latter'are held in position.

As already stated, the lower window-sash 1 is connected by hinges 13 with the weighted frame 12. This sash when in its upper position can therefore be opened inward after the side rails 28 have been turned back. It may also be arranged that the middle and upper sashes can be opened inward after the side rails have been turned back. For this purpose the middle sash 2 is provided at each side with a fillet 36, guided in the windowframe. This fillet is connected with the sash 2 and extends upward beyond it. Between the upward extensions of these fillets the upper sash 3 is guided. At their lower ends these fillets carry pins 37, which slide in grooves 38, Fig. 1a, of the window-frame 4. When the sashes 2 and 3 are in their lowest positions, Figs. 1, 1, and 2, and the rails 28 have been turned back, the pins 37, turning on the lower ends of the grooves 38, serve as pivots upon which the fillets 36 can be turned inward, carrying with them the sashes 2 and 3.
